Seagate Skyhawk 4 TB, Video Internal Hard HDD – 3.5", SATA 6Gb/s, 256MB Cache, for DVR NVR Security Camera System, with in-house Rescue Services (ST4000VX016)

Working very well in my custom designed CCTV hybrid DVR. Review of Seagate Skyhawk 4TB ST4000VX016. Yes its a bit noisy seeking, but mine is in a cabinet in the garage so I don't mind at all, it might be a shade annoying in a quiet environment though. Performance is excellent, it holds up a constant fairly high record rate with easy, all the streams are smooth. Whilst also giving me really quick seeking and replay at the same time, the system just feels smoother and snappier. Beware, there is another version around that is a tiny bit cheaper, the ST4000VXZ16 - note the 'Z' in the code, it has only a quarter of the cache of this version and other changes. For a couple of quid more, this one (without the 'Z') is the one you want. To early to tell on life expectancy, these things do have a really hard life in this application so you have to be a bit realistic.

Very easy to fit in my cctv box, so happy with it

Used in Reolink NVR: I like Seagate Skyhawk and this 8TB HDD was available at a reasonable price. I couldn't find any particular reason and the price of HDDs has been so variable that I wasn't that surprised. When buying HDDs the capacity doesn't aways reflect on the relative value so I use the cost per Terrabyte (Price divided by TB) and usually for a surveillance HDD it is about £20.60/TB and this was £18.40/TB. So I bought it. It came in a sealed static-protective bag. It was only then I saw "Factory Recertified" on the label. I am not unduly fussed and if it is official then fine. (I have used generic (not Seagate) renewed HDDs previously and a couple failed so I stick to new discs). No worries, I will try it out. The thing about CCTV disc fails whether used or new, and it happens very very rarely, is you cannot get a refund without falling foul of the privacy rules if you return a load of images of people to big organisation outside your Data Controller remit. I am docking one point because it took me a good five minutes trying to find the information that it was renewed. Amazon always put 'renewed' in the title so that anyone, even without specialist vocabulary. I feel duped.

Absolutely 5 star. At the moment the first star is having a rest. Came much faster than anticipated. The replacement recorder for my CCTV was £850. My brilliant son matched the hard drive and swapped it for under £60. Only down side is you need a brilliant son…..

Exact direct replacement. Ordered Sunday evening arrived Tuesday. CCTV working again.

HD used for cctv system and still going strong. Great value.

Easy to fit works great

Unfortunately the hard drive kept showing an error code and making a clicking noise and had to be returned

La rapidez costo , duración y velocidad

I don’t have any problems with this hard drive. It replaced a much smaller one that just gave up. I am glad we got this one. The storage is great. Quality of the pictures and videos are very good. It was easy to install and we have had it for much longer than the original one.

L'Hard Disck è perfetto ! capiente, veloce, silenzioso ed accessibile come prezzo !

Defective disk sent and amazon refused return.

Good
